Redis 基本操作

• 启动

启动server:redis-server.exe redis.windows.conf
启动client:redis-cli.exe -h 127.0.0.1 -p 6379

• 配置

--get all config 
config get *
config get configname

--set config
config set configname configvalue

• Abount key

-- key
set key value    --set key and value
del key          -- delete key
exists key       -- if exists
expire aaa 10    -- set the timeout 10s
pexpire aaa 5000  -- set timeout 5000mm
expireat aaa 1504771560  --set timeout at unixstamp
ttl key --show the seconds left before expire
rename key key1
